'CONDUCTORS PUNCH.

SPECIFICATION forming part of Letters Patent No. 736,116, dated August11, 1903. Application filed February 11, 1903. Serial No. 142,840. (Nomodel.)

T on whom it may concern! Be it known that I, RICHARD J. KRAUT- HEIM, acitizen of the United States, residing at Newark, in the county of Essexand State of New Jersey, have invented and produced a new and originalImprovement in Conductors Punches; and I do herebydeclare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make andusethe same, reference being had tothe accompanying drawings, and toletters r the durability of a punch and to render the of referencemarked thereon, which-form a part of this specification.

The objects of the invention are to increase same more positiveinitsaction, to facilitate the construction and to reduce the cost there of,and to secure other advantages and results, some of which may bereferred to hereinafter in connection with the description of.

the working parts. I

The invention consists in the improved conductors punch and in thearrangements and combinations of parts of the same, all substantially aswill be hereinafter set forth and finally embraced in the clauses of theclaim. Referring to the accompanying drawings, in which like letters ofreference indicate corresponding parts in each of the several figures,Figure 1 is a plan of the improved punch. Fig. 2 is a section of thesame, taken at line 00 of Fig. 1. Fig. 3 is a side elevation of aforward part of said punch; and Fig. 4 is a sectional detail taken atline y, Fig. 3. Fig. 5 is a plan and section of a female die-section.

In said drawings, a and b indicate, respec-' tively, the male and femalemembers of the punch, of which the female member 1) consists of acasting which is horizontally cut by a saw or otherwise split, as at c,to provide a narrow receptacle for the ticket or card to be verticallyperforated, as at g, and is countersunk on the upper side, and thusprovides a punchedwith relation to the dies.

' seat h for the female die 2', the seat being formed, as shown in Fig.4, by boring into the upper side of the prong to form a round aperture,into which is fitted the said die member. The said female die 1' isdisk-shaped and recessed at one side, as atj, and is fastened into theboring or aperture by forcing the metal 70, forming the side walls ofthe aperture, into the recess j, as indicated in Fig. 4. The inner wallof the recess is inclined, as shown in Fig. 5. By this construction thesaid female die is seated with great exactness and security and at acomparatively small expense of time and labor.

The prong d is slotted vertically to receive the section or member a,the slot Z being enlarged near the forward extremity of the prong, as atm, to provide a round sightopening, by means of which the conductor-cansee the position of the card or ticket to be Heretoforethissight-opening m has been extended at the sides of the male member a to apoint distant a half-inch from the male die n. In the present case theside walls 0 o of the slot Z extend parallel and in contact with themember a up to a point vertically in line with the inner part of themale die n, of the punch, and thus there is no chance of the handledmember a at its forward extremity springing laterally when punching, andthus preventing a proper entrance of the male die into the female die toefiect an exact and perfect punching operation, and, furthermore,because of the long bearings for the forward extremity of the member athere is less op- 'portunity to wear the said side walls of the member12 away, and thus permit a lateral looseness of the members inimical toa proper punching operation.

The members a and b are pivoted or ful-.

male member, the walls of the slot extending at the sides of, and incontact with the male member to the line of the die thereof, and, at

, said line, the said slot being laterally enlarged to form asight-opening around the extremity of the male member to permit theentrance of light to the ticket as the same is about to be punched,substantially as set forth.

2. The improved punch herein described, comprising the pivoted andhandled members, each provided with a punching-die, the male memberhaving a slot with a round enlargement at its forward end, the saidenlargement forming a sight-opening, and the parallel-sided side wallsof the slot extending along the sides of and in contact with the malemember up to the sight-opening immediately
